In being able to close the gap with it, it's Ward, Golovkin is a close second and then Cotto. Ward's is very powerful and his opponents usually don't respond very well to it.

As for variation, being able to do the most with it, it's Mayweather, then Ward. Both of them jab to the body and know how to quickly switch over to the hook.
